Using this soap dispenser is easy. First, choose your preferred power supply option - either a battery pack (4xAA alkaline) or an A/C Adapter. Then, fill the 70.5oz top - fill soap tank with any non - proprietary bulk foam soap. Place your hand under the spout, and the touch - free infrared sensor will dispense soap. Make sure to keep the area around the sensor clean to avoid false activations. For maintenance, regularly check the indicator light at the base of the spout. If it shows low soap, refill the tank. If you have the multi - station system, ensure all connections are secure. Also, clean the spout and the dispenser body with a mild cleaner to keep the brushed brass finish looking great. This dispenser is vandal - resistant, but avoid any rough handling. It complies with ADA guidelines, so use it with confidence knowing it meets safety standards.
